MC Enterprises Hydro Flame Furnace Limit Switch | Normally Open, Screw Terminal

The limit switch on a Hydro Flame furnace is a key safety component, cutting power to the burner if the unit overheats. When this switch fails, a furnace can shut down unexpectedly or fail to fire at all. This MC Enterprises replacement is built to the same automatic, normally-open operation as the original.

• Normally-open limit switch with automatic operation
• Screw terminal connections for a simple wiring swap
• Copper contacts in a compact 1.25-inch square housing
• Panel-mount design matches typical furnace installations

If your furnace is cutting out early or not responding correctly during startup, a worn limit switch is a common culprit worth ruling out.
